COMBINED STRIKER AND BUMPER FOR DOORS.

Application filed April 2, 1915.

T 0 all whom it may concern.

Be it known that 1, JOHN FRANK STRE- nnnenn, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Combined Strikers and Bumpers for Doors, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to a combined striker and bumper for doors, more particularly adapted for use with automobile doors, and an object of the invention is a simple and inexpensive device which may be applied as a unit to the door-jamb so arranged as to absorb shock incident to the shutting of the door and also adapted to hold the tongue of the door lock in engagement with its catch to prevent rattling thereof. These objects and the novel features of construction are hereinafter more fully described and claimed as shown in the accompanying drawings in which Figure 1 is a perspective view of a striker and bumper plate embodying my invention. Fig. 2 is a section taken through the striker plate and bumper showing the door and door-jamb in dotted lines.

Like characters of reference refer to like parts throughout the drawings and specificatlon.

In the preferred form of the invention shown in the drawings, the striker plate 1 is provided with a usual curved tongue 2 adapted to engage the tongue of the door look upon the closing of the door to retract the same for engagement in the aperture 3 in the plate, as is usual in commonly known striker plates. The striker plate is also provided with an integrally formed bumper plate 4: extending at an angle thereto to fit the angle between the door stop and frame. This bent portion 4 is apertured at 5 substantially parallel with the center line of the aperture 3, and projecting through this aperture is a plunger 6 adapted to engage against the door when closed and to hold the tongue of the door lock against the edge of the aperture 3, as indicated in dotted lines in Fig. 2.

As indicated in Fig. 2, the plunger or Specification of Letters Patent.

Serial No. 18,640.

bumper 6 is preferably made hollow and is provided with an external circumferential flange 7 to prevent its being forced through the aperture 5. At the back of the bumper plate 4. is secured a plate 8 and this plate is provided with a recess or pocket 9 into which the plunger may be forced on closing of the door. A spring 10 is positioned in the recess and extends into the hollow plunger 6 as shown tending to force the plunger outward through the aperture 5. By making the plunger hollow a comparatively long coiled spring may be utilized without the necessity of providing a deep pocket therefor.

As will be noted in Fig. 2, the door-jamb is provided with a flange preferably mortised to receive the bumper member 4 and plate 8. As this flange is of little thickness and strength, the bumper plate provides a means to relieve the flange of shock upon closing of the door. The spring pressed plunger 6 also tends to ease the shock of closing the door and even though the plate 4: be struck in such operation the strain is ab sorbed by the striker plate and not transmitted to the said flange. The plunger also holds the door with the tongue of the lock in engagement with the edge of the apertur 3 and prevents a rattling thereof.

The striker and bumper being formed as a unit, as shown, less labor is involved in applying the device to a door-jamb than if separate instrumentalities were utilized as is usual. The device formed as shown, is also less expensive to manufacture.

Having thus briefly described my inven tion and its utility, what I claim and desire to secure by Letters Patent of the United States is- 1. A striker and bumper for doors comprising an apertured striker plate, a bumper plate extending at an angle thereto at the rear edge, said bumper plate having an aperture, a plate secured at the back of the bumper plate provided with a pocket covering the aperture, a plunger in the aperture, and a spring in the pocket engaging said plunger.

2. A striker and bumper plate for doors comprising an apertured striker plate, a bumper plate extending at anangle thereto at the rear edge, said bumper plate having an aperture, a spring sustaining member at the rear of the aperture, a plunger in said aperture, said plunger having a flange greater in diameter than the aperture to prevent the plunger from passing therethrough, and a spring supported by the sustaining member and engaging the plunger.

3. A striker and bumper plate for doors comprising an apertured striker plate, a bumper plate extending at an angle thereto at the rear edge, said bumper plate having an aperture, a pocket provided at the rear prising an apertured striker plate, a bumper plate extending at an angle thereto and provided with an aperture, a sustaining member at the rear of said aperture, and a yield able member carried by the sustaining member, said yieldable member including a portion extending through the aperture in the bumper plate adapted to engage against the door when closed.

In testimony whereof, I sign this specification in the presence of two witnesses.

JOHN F RANK STREBERGER.
